/**
 * The object registry manages a collection of global singleton objects.
 * However, it differs from the standard singleton pattern in a few important
 * ways: - The objects managed by the registry have an undefined lifetime. They
 * may become invalid at any time, and they may not be valid at the beginning of
 * the program. - The only object that is always guaranteed to be valid is the
 * ObjectRegistry itself. - There may be more than one ObjectRegistry, and there
 * may be more than one instance of any of the systems managed by ObjectRegistry
 * allocated at once. For example, separate threads may maintain their own
 * separate ObjectRegistry instances.
